所以我要创建的图表是一张图表，其中约130个点的数据在一秒钟内正在流动。现在，假设我有一个要在Highchart中渲染的1000个元素的数组。
我能够用数组的1000个元素渲染Highchart，但是问题是，在数组结束之后，Highchart没有停止。它一直在运行。
我只想在Highchart到达数组末尾时停止。
这是我尝试过的代码
var data = [7,10,8,6,8,2,5,2,2,2,3,4,4,10,6,10,5,10,0,2,9,5,7,0,5,0,5,7,8,7,5,1,9,1,5,7,10,3,7,0,2,10,8,8,1,1,0,7,6,3,1,10,0,8,3,5,5,10,3,8,4,0,3,5,8,7,0,0,0,8,7,3,2,1,0,6,7,7,3,7,5,0,1,0,0,4,9,4,4,3,0,2,10,9,0,2,7,6,5,9,0,6,7,9,0,6,2,7,1,6,5,1,3,1,0,5,0,4,2,7,2,0,7,0,3,10,6,3,4,9,9,10,10,9,5,9,8,5,3,2,5,9,5,10,10,7,8,3,8,9,5,3,9,0,1,2,6,4,1,9,0,5,0,5,6,4,1,1,3,8,2,0,7,6,4,0,6,5,5,6,4,6,6,3,3,5,5,8,7,3,4,7,5,6,1,4,2,4,7,9,8,4,0,3,8,6,2,6,10,8,10,1,10,8,6,8,8,3,8,7,8,6,7,10,9,10,0,7,7,8,1,10,1,4,7,10,7,0,9,6,3,3,3,1,4,3,4,5,0,5,9,0,6,1,8,5,1,8,9,4,0,4,5,4,3,8,2,10,5,9,4,9,5,3,6,5,7,2,2,7,1,1,9,7,4,1,7,5,2,10,6,4,3,5,7,2,4,5,7,3,2,0,8,5,5,7,8,2,9,5,9,1,2,0,7,8,10,5,6,9,2,5,1,9,4,0,7,4,4,7,10,0,8,6,0,6,4,4,8,3,9,1,3,0,0,4,4,2,5,3,3,6,1,4,6,6,4,9,7,0,2,2,1,2,2,6,2,0,2,5,7,8,8,1,7,3,9,0,0,0,9,4,9,8,9,7,10,8,2,0,5,10,10,0,1,7,5,9,2,8,10,10,4,6,6,6,10,10,5,1,5,2,1,9,3,2,5,3,1,3,10,7,1,3,5,3,0,6,7,5,1,10,5,9,0,9,2,3,0,10,0,6,9,8,3,8,7,0,10,4,2,2,5,6,7,0,10,10,9,9,8,6,10,5,9,0,6,4,8,5,0,4,4,4,1,8,3,0,9,3,3,9,1,5,0,10,1,1,3,10,6,5,8,0,6,5,2,7,10,4,2,0,10,1,7,6,2,0,1,6,10,10,6,6,10,1,4,7,5,6,5,4,1,5,6,9,1,8,4,7,2,8,5,9,7,3,9,2,2,8,10,6,10,10,7,8,7,2,6,8,7,4,6,1,5,9,2,0,5,4,4,0,4,5,7,2,3,8,9,1,0,8,6,10,8,3,7,3,3,6,7,2,7,6,6,2,8,6,9,6,8,5,4,8,4,6,7,9,8,7,8,5,8,2,0,8,5,0,5,2,8,4,7,0,7,1,4,8,10,8,2,5,10,9,1,9,3,0,6,9,2,10,5,1,4,0,4,9,1,1,3,5,0,5,5,2,5,1,1,7,0,2,6,8,10,7,9,3,0,9,4,2,4,6,2,2,9,2,7,3,6,6,9,2,2,0,2,9,1,5,7,10,10,1,8,5,9,9,4,1,7,1,0,0,6,7,7,7,2,9,9,2,10,5,4,2,3,10,9,9,7,1,1,6,8,4,9,6,7,4,9,4,2,7,6,2,6,0,1,5,5,8,9,5,1,7,8,7,3,2,3,1,1,2,5,6,4,10,8,10,3,3,1,0,6,7,0,7,4,8,4,7,6,0,7,1,2,3,10,4,1,10,7,9,4,7,7,10,10,10,6,8,9,7,3,10,9,0,3,6,2,10,5,3,6,8,5,0,2,3,1,6,9,10,9,10,7,5,8,7,4,4,3,10,2,3,4,3,10,8,5,9,8,5,6,2,4,9,1,5,0,7,1,1,4,4,10,4,7,8,8,9,7,1,9,5,5,4,3,0,0,9,5,6,3,3,4,6,1,2,6,2,8,4,10,0,9,1,10,2,7,3,6,3,9,2,3,5,7,8,1,1,9,3,4,6,7,6,2,2,8,0,10,3,3,5,7,4,1,3,9,5,4,3,3,2,9,8,7,8,7,6,8,7,7,1,2,10,10,2,9,3,2,3,2,9,9,0,3,0,4,9,6,0,1,6,9,5,8,7,9,5,6,8,3,5,3,4,9,8,0,3,4,8,6,9,4,7,1,9,8,0,4,8,1,0,7,3,3,1,6,9,9,5,4,3,8,8,9,10,4,9,0,7,8,6,9,8,4,10,4,1,2,5,4,0,6,4,1];
var json_array = data ;
var i = 0;
function next() {
return json_array[i++];
// i++;
}
Highcharts.chart('container', {
chart: {

marginRight: 10,
events: {
load: function() {
// set up the updating of the chart each second
var series = this.series[0],
chart = this;
var count = 0 ;
setInterval(function() {
var x = (new Date()).getTime(), // current time
y =next();
console.log(y) ;
series.addPoint([x, y], false, true);
chart.redraw(false);
}, 1000/130);
}

},

data: (function() {
// generate an array of random data
var data = [],
time = (new Date()).getTime(),
i;
for (i = -1000 ; i <= 0; i += 1) {
data.push([
time + i * 10,
null
]);
}
return data;
}())
}]
});
我也为此创建了一个小提琴，如下所示。
仅在到达数组的最后一个元素时清除Interval。请查看以下代码。
var draw = setInterval(function() {
var x = (new Date()).getTime(), // current time
y =next();
console.log(y) ;
if (i == data.length) {
clearInterval(draw);
return;
}
series.addPoint([x, y], false, true);
chart.redraw(false);
}, 1000/130);这里是小提琴代码链接。https://jsfiddle.net/geekcode/8nL53x01/1/
